Tripping, falling, stiff, and now sudden onset of rearing in 4 y/o OTTB

My mare is 4 rising 5 OTTB. When I got her in the summer she had already competed some low level shows in the hunter ring. She was (until recently) a dream to work with. Sweet, willing, and unflappable. A true barn favourite.

In November she started tripping ALOT. Like 5 or 6 times a ride. She would trip at a walk or trot, on grass or on sand. I didn’t pay much attention to it because she is so lovely to work with and she had low heels that my ferrier and I were working on correcting slowly. Beginning of January she started spooking hard at very strange times for no reason, and was also very unwilling to trot a circle. She’d try to stop whenever I asked her to circle. It’s also very difficult to lunge her because she’s started exploding on the lunge line at anything more than a walk (rearing, striking out, bucking, running backwards). Which I have to reiterate is strange for her because of how solid she is. I chalked it up to the fact we had been in the indoor arena so much in the last two months because of Canadian winter.

At the Beginning of February she tripped at a walk and went down onto her knees, while walking in the arena under saddle. I was worried, but I was also about to get her feet trimmed so I let it go again…

middle of Feb now and she has refused all work. She plants herself and when asked to move forward she rears and multiple times in a row. I put her on a probiotic think g maybe it was ulcers and started giving her Acid FX before we rode. No effect. She hasn’t flipped yet, but it’s been close a few times. Now at the end of February I’ve gotten a dentist out to get her teeth floated (she had some mild ulcerations and sharp enamels). She also blew an abscess that same day the dentis came out. I gave her a few days off and got out a chiropractor to see if there was any pinching etc. Chiro said nothing major, just some tightness in her pole, though she isn’t convinced it would cause that level of reaction. I gave her banamine for two days and gave her 4 days off. However now, just handwalking her she rears and spooks, trips herself, and strikes out.

I cant say enough how out of nature this is for her. She was a happy go lucky, try her hardest, life loving girl and it seems she so angry about life now. I’m concerned it may be neurological. However I’ve never heard of wobblers resulting in sudden onset of rearing. Has any one had any experience with that? If she isn’t any different with a few more days off, I’m going to call the vet in and get a neurological check done.

Any words of advice would be appreciated

This sounds VERY neuro. EPM, neck issues, something is very wrong. Please get your vet out ASAP, and stay safe until then.

If this was a horse in northern Virginia, most vets would treat for lyme or EPM. They don’t always test positive for them though even if they have them but they will absolutely cause these symptoms!

I also wouldn’t wait. Something is very wrong.

Spooking could be a vision thing.

The antics on the lunge could be a number of things.

Feet planting could be pain related or training related.

Are you working on your own or under the supervision of a trainer? If working with a trainer, what does she say?

But above all else, I would suspect a neuro issue. Get a vet involved. If it is a neuro issue that involves EPM or Lymes you will want to to treat it ASAP before the disease causes permanent damage.

Best of luck!!

Hi Everyone,

thank you for the words of advice. I was worried that I was being dramatic and overzealous thinking Neuro…I guess I need to learn how to follow those instincts. I will give the vet a call tomorrow morning and have them come out ASAP.

You ask about wobblers and if anyone has seen it manifest itself in sudden rearing. A friend of mine had an OTTB that did. He became difficult and dangerous to handle in a short period of time. I would not wait on calling the vet either. Please be careful when you are handling her.

It really is a few months past time to have your vet out, so call first thing Monday. Hopefully this is “just” EPM or Lyme and not wobblers or a malformation of some cervical vertebrae.

Never think you’re overly worried when it comes to a big animal not able to keep its feet :wink:

oh interesting. I knew about tripping, being unbalanced, and spookiness, but I didn’t realize it could manifest as sudden onset dangerous behavior such as rearing etc. I’m sure you understand it’s tough because it’s while on the ground and not just in the saddle. As I mentioned above I’m definitely getting the vet out tomorrow. I don’t need anyone being hurt by her.

Glad you’re getting the vet out. I agree with everyone else that this is likely a neuro issue. Please keep us updated on your sweet girl! Jingles for you and her!

The first fall I had my gelding he started displaying some of the behaviors you talk about like sudden spookiness and unwilling to go forward. He went from a pretty chill dude to being terrified of black buckets and unable to cross pass center of ring. He became so dangerous and unpredictable on the ground I considered having him put down. Ended up being ulcers and within 5 days of treatment became his usual self. He had some trouble with tripping but his feet weren’t in great shape when I got him and he had very poor muscle tone. But I also think he was distracted by pain.

I’d suggest maybe trying Nexium to see if it has a positive effect. I know it sounds a bit ridiculous but ulcers can cover a multitude of problems. But I’d still get vet out for opinion

I totally get the importance of watching for ulcers. I actually put her on a probiotic as well as acid fx as soon as I noticed her crankiness increase (so she’s been on those for 2 weeks now). That was my first thought too… but the behavior had only increased.I have the vet coming tomorrow morning so we’ll see what they say!

This sounds like she’s experiencing some sort of pain. It has more to do than just her feet. Get a full check from a vet, it will be costly. Also you need to go the extra miles to have her saddle properly fitted, get a chiropractor, etc. etc. etc. go back to the basics. Maybe take her for walks in the arena but don’t ride or lunge her until you have results. Good luck

Ulcers don’t make a horse stumble repeatedly and fall down. It’s nice to think there’s an easy, inexpensive over the counter treatment that will stop a horse from tripping and falling. But there isn’t. This horse needs a vet yesterday and that vet needs to pull blood and get some lab work done.

My guess is EPM or Lyme. Hopefully it is one of those, the other possibilities are far more complicated to diagnose and treat.

Sadly I agree.
My second horse Melly, an OTTB, reared, for no discernable reason… on lunge, in hand, on X-ties… and he got light when under-saddle as well.
He died after 8 months from EHV-1 neuro. That is not something anyone or any horse should have to go through. Ever.
I would get the Vet to do a thorough check…

I’m not sure what wat hung and acid FX is.
I have ulcers. If I was only given probiotics, aloe vera juice or other less efficacious treaments, I would be beyond miserable.

I want to support the op and I am glad the vet is coming out, but, that said, I am aghast that the vet was not called in months ago. Hopefully, one of the things that the op will learn from this is that our horses talk to us, and it is our responsibility to listen. Your lovely horse started talking to you the minute her behavior/way of going changed. By now she is SCREAMING at you. "I hurt. Something is wrong. HELP me!!!,
She is now a danger to herself and those around her. Do not ride or lunge her. Until the vet comes, any time you work around her have someone nearby in case she goes down. This is very, very serious. Please take it seriously.
Sadly I know what I am talking about 2 years ago I had to put down my wonderful 6 year old. In 2 weeks he went from fine to dangerous. His Neuro status went downhill so quickly that the head of neurolgy at New Bolton told me he was too dangerous to go into his stall because he might fall over on someone. He was euthanized that day.
Lest people think I am being dramatic and scaring the op, yes I am. I do not know how else to impress upon her the seriousness of having allowed her horse to go this long without being treated by a vet.

Lord Helpus, Similarly I wish I had known more [iow someone had alerted me to the neuro symptoms to look out for] so that I could have known sooner what Melly was going through and I could have had him put down.

I had a Vet involved, but Melly went downhill in a matter of hours, it was horrifying to watch, and the helplessness because the Vet was far away on a call and the fact that Melly got dangerous near the end… made it worse.
Had I realized that those early symptoms [head pressing, the tongue hanging, etc] meant something, I could have avoided any of us suffering through it.
